Hi, first time poster so I'm not sure how to start this but I have a male bearded dragon that I got from a friend back in November of last year. He just turned a year old and when I had his out the other night I noticed an oddity with a part of his scales on his side/back and I'm worried about the possibility of scale rot. His humidity stays at around 30-40%. So far his appetite is normal and he's not lethargic. I actually took him to the vet and she said that based on her observation he has mites but she didn't actually see any. He has no bites from any and I've never seen any in his enclosure. I gave him a bath tonight and no mites came off of him. So I'm wondering if he truly has mites. Any assistance would be greatly appreciated. Posting pictures as well.
